Nearly a decade ago, HBO ran an ad depicting the Klitschko brothers plotting world domination -- in boxing terms. The dream of four major belts in the family came true July 2 after Wladimir defeated David Haye to add the WBA belt to the IBF and WBO straps and swatted away one of the two biggest threats to their empire. On Saturday, WBC king Vitali takes on the other in Tomasz Adamek -- in Adamek's native Poland. Vitali is attempting to become only the second 40-or-older heavyweight champ to successfully defend his title. The 46 yr-old George Foreman is the other (4/22/95 W 12 Axel Schulz). Adamek is attempting to become the sixth cruiserweight/light heavyweight champ to win the heavyweight title (Michael Spinks, Roy Jones, Evander Holyfield, Michael Moorer & David Haye).

Will Big Brother maintain the siblings' iron grip or will Adamek shake the world by slaying this giant? The oddsmakers say Vitali, installing him as a better than 5 ½-1 favorite. These CompuBox factors lay out what each has done recently and the challenges that face them.
